Answers
The ratio of product conc. to reactant conc. is calculated. the equilibrium constant for the reaction at 500 °C is 0.161 mol⁻² L².
How to calculate ?The balanced equation for the reaction is
N₂(g) + 3H₂(g) ⇄ 2NH₃(g)
The equilibrium constant written as
k = [NH₃(g)]² / [N₂(g)][H₂(g)]³
The given concentration are at equilibrium state. Hence, we can use directly for calculation.
[NH₃(g)] = 0.602 mol/L
[N₂(g)] = 0.420 mol/L
[H₂(g)] = 0.113 mol/L
By applying the formula,
k = (0.602 mol/L)² / ((0.420 mol/L) x (0.113 mol/L)³)
k = 0.161 mol⁻² L²
Hence, the equilibrium constant for the reaction at 500 °C is 0.161 mol⁻² L².
How can equilibrium constant be calculated?The concentrations of each component participating in a single reaction are measured after it has reached equilibrium in order to determine the numerical value of the equilibrium constant. Calculations are made to determine the ratio of reactant concentrations to product concentrations.
In what do Q and K balance?As a reactive system gets closer to equilibrium, a quantity called Q changes. When equilibrium is attained and the reaction is said to have "ended," K is Q's numerical value.

per year. calculate tons of mercury in the coal based on the lower (50.0 ppb) and higher (200.0 ppb) concentrations.
mercury at 50.0 ppb= __ tons hg
mercury at 200.0 ppb= __ tons hg
Answers
The amount of mercury at 200.0 ppb is 0.478 tons of mercury.
The amount of mercury at 50.0 ppb is 0.1195 tons of mercury.
The question states that mercury is present in trace amounts in coal, ranging from 50.0 to 200.0 ppb.
A typical power plant burns 2.39 million tons of coal per year.To calculate the amount of mercury at 50.0 ppb, we first need to convert ppb (parts per billion) to tons. We can do this by multiplying the concentration by the total amount of coal burned:50.0 ppb x 2.39 million tons = 0.1195 tons of mercury.
Therefore, the amount of mercury at 50.0 ppb is 0.1195 tons of mercury.To calculate the amount of mercury at 200.0 ppb, we can use the same formula:
200.0 ppb x 2.39 million tons = 0.478 tons of mercury.
Therefore, Overall, to calculate the amount of mercury in coal based on different concentrations, we can use the formula concentration x total amount of coal burned.

The term Ksp denotes the solubility product. It is generally used to predict the precipitation of reactions. The Ksp of PbSO₄ is 6.24 × 10⁻⁷.
What is solubility product?The solubility product of a sparingly soluble salt is defined as the product of the molar concentrations of its ions in a saturated solution of it at a given temperature. By knowing the solubility product of a substance, it is possible to predict whether a substance precipitate out or not.
In short, the precipitation of an ionic substance from the solution occurs when the ionic product exceeds the value of its solubility product at that temperature.
Here PbSO₄ dissociates as:
PbSO₄ → Pb²⁺ (aq) + SO₄²⁻ (aq)
Ksp = [Pb²⁺] [SO₄²⁻ ]
= [7. 9 × 10⁻⁴] [7. 9 × 10⁻⁴]
= 6.24 × 10⁻⁷
Thus the value of Ksp is 6.24 × 10⁻⁷.

Calculate the volume of water in liters which the student needs. Round your answer to the nearest 0.1 L. ol.2 cm
M
flask
OL
6
water
Answers
Answer:
The required volume of water the student needs is 4.9 litres of water
Explanation:
From the diagram related to the question, we have;
The dimensions of the tank are;
Length of tank = 24.0 cm = 0.24 m
Width of tank = 21.0 cm = 0.21 m
Depth of tank = 13.0 cm. = 0.13 m
Allowance provided between the top of the tank and the top of the water = 2.0 cm
Diameter of the round bottom flask, D = 10.5 cm = 0.105 m
Therefore, the radius of the round bottom flask, r = 0.105/2 = 0.0525 m
Therefore we have;
Depth of water in the tank = Depth of tank - Allowance provided between the top of the tank and the top of the water
∴ Depth of water in the tank = 13.0 - 2.0 = 11.0 cm = 0.11 m
Given that the flask is immersed in the water contained in the tank to raise the tank water level, we have;
Volume of water + Volume of flask in the tank = Length of tank × Width of tank × Depth of water in the tank
Volume of water + Volume of flask in the tank = 0.24 × 0.21 × 0.11 = 0.005544 m³ = 0.005544 m³× 1000 l/m³ = 5.544 l
The volume of the spherical flask = 4/3·π·r³ = 4/3·π·0.0525³ = 6.06×10⁻⁴ m³ = 6.06×10⁻⁴ m³ × 1000 l/m³ = 0.606 l
The required volume of water the student needs , V = Volume of water + Volume of flask in the tank - The volume of the spherical flask = 5.544 l - 0.606 l = 4.9 l.

Electronic configuration entails the arrangement of electrons within an atom. Therefore, to do this, we must know the number of electrons in the element given.
since we have been given oxygen atom, the number of electrons therein is 8.
So;
the electronic configuration is 2,6
2.
The atomic number of an atom is the same as the number of protons that it contains. The proton number is the number of positively charged particles in the atom of the element.
Since we have been given that the number of protons within the atom is 6, therefore, the atomic number is 6.

A buffer solution contains 0.376 m ammonium chloride and 0.366 m ammonia. if 0.0486 moles of potassium hydroxide are added to 225 ml of this buffer, The ph of the resulting solution is 9.18
Milli moles of NH3 = 0.366 x 225 = 82.35
milli moles of NH4CL = 0.376 x 225 = 84.6
milli moles of KOH = 0.0486
pOH = pKb + log[salt -c /base +c]

Answers
The volume of air at 273 K would be 0.67 L by Gas Law. The ideal gas law, a state equation for all gases, states: PV is equal to nRT, where n is the number of moles of the gas and 8.314 joules per kelvin per mole is the universal (or perfect) gas constant.
According to the Ideal Gas Law, all gases have an equal number of molecules when they are at the same temperature, pressure, and volume (but not the same mass)
V1=0.5 L
T1=203 K
T2 = 273 K
V2 = unknown.
Now, \(\frac{V1}{T1}\) = \(\frac{V2}{T2}\)

The calorimeter constant when 51.203g of water at 55.2c is added to a calorimeter containing 49.783g of water at 23.5c and for the system to equilibrate, the final temperature reached is 37.6c is 9.67J/gc.
Given mass of water (m1) = 51.203g
Temperature of water (T1) = 55.2c
mass of water (m2) = 49.783g
Temperature of water (T2) = 37.6c
the final temperature reached is = 37.6c
We know that specific heat (Q) = mCpΔT where m is mass Cp is latent heat and ΔT is change in temperature.
So Qwater = 51.203 x 4.184 x (23.5 - 55.2) = 6791.9J
Qcalo = 49.783 x Cp x (23.5 - 37.6) = 701.9 x Cp
Given that Qwater = Qcalo
6791.9J = 701.9 x Cp

reacts with acid to form hydrogen physical or chemical property
Answers
The reactivity of substances with acids is a chemical property. When a substance reacts with an acid, it can produce hydrogen gas.
The reactivity of substances with acids is an important concept in chemistry. When a substance reacts with an acid, it can undergo a chemical reaction that produces hydrogen gas. This reaction is a chemical property of the substance.
Acids are substances that can donate protons (H+) in a chemical reaction. When a substance reacts with an acid, it can accept the protons from the acid and release hydrogen gas. The reaction can be represented by the general equation:
Substance + Acid → Hydrogen gas + Other products
For example, when metals such as zinc or magnesium react with hydrochloric acid (HCl), they produce hydrogen gas:
Zinc + Hydrochloric acid → Zinc chloride + Hydrogen gas
This reaction is a chemical property because it involves a change in the chemical composition of the substance. It is important to note that not all substances react with acids to produce hydrogen gas, as the reactivity depends on the specific chemical properties of the substance.
